Epoxy

Application Description

• Electrostatic Spray
• Coating can be applied with automatic and manual devices.
• Substrate should be correctly cleaned before use.
• Do not mix this product with other powder coatings.
• Color and finish influenced by film thickness: a good control of the film thickness will help the consistency of the aspect.
• It is recommended to partially cure or gel the primer if it will be overcoated with a topcoat and fully baked. 30-50% cure of primer is recommended to maximize intercoat adheasion.

Surface Preparation

• Surface preparation should be chosen according to the type of substrate and required performance.
  The coater should test the suitability of the surface preparation before the application using appropriate test methods.
  
  For steel with mill scale, chemically clean or abrasive blast. Chemically clean using an acid descale stage after alkaline cleaning and rinsing before pretreatment. The acid choice would depend on the severity of the scale to be removed. Time and temperature would also depend on the acid choice and the scale to be removed. Abrasive blast to ISO- Sa2½ or minimum SSPC SP-6, power tool clean to ISO-St3 (SSPC SP-3), or hand tool clean to ISO-St2 (SSPC SP-2).
  
  For cold rolled steel, a suitable multi-stage chemical conversion is needed.
